API602 API622 API624 Forged Swing Check Valve A105N 3/4 Inch Dn20 800LB Sw Asme 16.34 Full Bore Bolted Bonnet

Forged Steel Check Valve

VERVO forged steel check valves are offered in swing type, lift type, bolted bonnet and welded bonnet design in a wide range of carbon, stainless steel, duplex stainless steel, alloy and other special materials. VERVO forged steel check valves are manufactured according to API 602 Design.

Forged check valve is to provide with single disc. With the force of medium, the disc will automatically open or close around the fixed pin shaft. When the media stops the flow, the disc will be closed under its own force. No manual intervention is involved in the whole process.

Check valve is mainly to prevent the media reverse flow and ensure one-way flow of media channels only. It prevents accidents while a sudden loss of power in the pipeline medium such as the power equipment like pump damages, and the medium reserve flow against power source.
